Çalışma Belleği Kapasitesi Yüksek ve Düşük Bireylerde Duyu Profilinin Karşılaştırılması

Öz

Mevcut araştırmada farklı çalışma belleği kapasitesine sahip bireylerde duyusal işleme özelliklerinin incelenmesi amaçlanmıştır. Bu doğrultuda çalışma belleği kapasitesi yüksek ve düşük gruplar duyu profilleri açısından karşılaştırılmıştır. Araştırmanın örneklemini 18-25 yaş arası 58 üniversite öğrencisi (31 kadın, 27 erkek) oluşturmuştur. Katılımcılar Harf Sayı Dizisi Testi (HSDT) puanlarına göre çalışma belleği kapasitesi yüksek ve düşük olarak iki gruba ayrılmıştır. Duyusal işleme özelliklerinin belirlenmesi amacıyla Adolesan/Yetişkin Duyu Profili (AYDP) kullanılmıştır. Bu profil düşük kayıt, duyusal kaçınma, duyusal hassasiyet ve duyusal arayış olmak üzere dört çeyrekten oluşmaktadır. Grupların çeyrek puanlar açısından karşılaştırılması amacıyla MANCOVA uygulanmıştır. Beck Depresyon Envanteri (BDE) puanları kontrol değişkeni olarak analize dahil edilmiştir. Genel MANCOVA sonuçlarına göre, duyu profili açısından gruplar arasında anlamlı fark bulunmamıştır (p > ,05). Yapılan tek değişkenli analizler sonucunda düşük kayıt, duyusal hassasiyet ve duyusal arayış çeyrekleri açısından anlamlı bir farklılaşma gözlenmemiştir (p > ,05). Duyusal kaçınma açısından iki grup arasında görülen fark (p = ,05) ise Bonferroni düzeltmesi sonrasında istatistiksel anlamlılığa ulaşmamıştır. Bu sonuç, gelecek araştırmalar tarafından test edilmesi gereken keşifsel bir bulgu olarak değerlendirilmiştir.

Sensory Profile Comparison in High and Low Working Memory Capacity

Öz

In the current research, it was aimed to examine sensory processing characteristics in individuals with different working memory capacity. Accordingly, groups with high and low working memory capacity were compared in terms of sensory profile. The sample of the study consisted of 58 university students (31 female, 27 male) between the ages of 18-25. The participants were divided into two groups according to the Letter Number Sequence Test (LNST) scores as high and low working memory capacity. Adolescent/Adult Sensory Profile (AASP) was used to determine sensory processing characteristics. This profile consists of four quadrants: low registration, sensation avoidance, sensory sensitivity, and sensation seeking. MANCOVA was conducted to compare the groups in terms of quartile scores. Beck Depression Inventory (BDI) scores were included in the analysis as control variable. The overall MANCOVA results did not show a significant difference between the groups in terms of sensory profile (p > .05). As a result of the univariate analyses, no significant group differences were observed for the low registration, sensory sensitivity, and sensation seeking quadrants (p > .05). The difference between the two groups in sensation avoidance (p = .05) did not reach statistical significance after the Bonferroni correction. This finding was considered exploratory and should be tested in future research.
